Specification of Letters Patent.

Patented Dec. 8, 1914;

, Application filed December 19, 1913.. Serial No. 807,672.

To all whom it may concern:

Be it known that I, EDWARD H. J nnvns, of the city of London, Province of Ontario,

Canada, have inventedcertain new and useful Improvements in Window-Screeh-Attaching Devices, of which the followingis a specification.

This invention relates to means for securring in place the detachable Window screens, now ordinarily employed, in such a manner that the window sash beneath which the screen. is used, may be closed when desired without the necessity of removing the screen from the window. I 1

I attain my object by "meansof-certain constructions and arrangements of the screen and the attachments which may be briefly described as followsz'A flanged metal strip is secured to each side of the screen, the flange extending from bottom to top of the screen at an angle to the plane ofits surface. Each strip is notched at its lower end to hook into a keeper securedto and behind one of the stops of the window frame. On

these keepers the screen may swing to bring its upper end into or out of position below the window sash.

A hook is secured at the back of the stop in a suitable manner to be engaged-by the flange of the strip on'the screen to limit the outward swing of the latter. The keeper and hook are preferably formed from the same metal strip which is suitably shaped to be secured to the stop. I

' The invention is illustrated in the accompanying drawings in which 1 i Figure l is a front elevation of a window provided with a screen having my attaching devices; Fig. 2a side elevation on an enlarged scale showing the attachments; Fig.

3 a front elevation of part of the same; Fig. 4 a perspective detail of the metal strip connected with the sides of the screen; and Fig; 5 a perspective detailof the plate connected with the sides of the window frame.

In the drawings likeletters of reference indicate corresponding parts in the different figures.

1 is a wire fly screen of the ordinary extension type.

2 are the stops of the window frame between which the sashes slide. Each side. of the screen is provided with an attachment comprising a metal strip 3 of substantially triangular form. as shown, which strip is provided with a flange 4. The metal strip is connected with the edge of the screen so that the flange is inclined to the plane of the surface of the screen. The screen is fitted between two of the stops 2 so that it may be swung on its lower end to bring its upper end to a position below the adjacent a window sash. When the screen is pushed from below the sash the latter may be lowered to the bottom. When the screen is swung in and the sash is resting on its top the flanges 4 fit against the outer faces of the stops 2 effectually closing any gap which might otherwise exist between the sidesof the screen and the stops. The flanges also serve to limit the inward movement of the screen. a I

Suitable pivotal connections are formed between the lower ends of the screen and the window frame by means of the following constructions: The strip 3 is split at the angle betwen the strip and the flange 4 to form the lower end of the latter' as a downwardly projecting tongue 5.v A keeper with which the tongue may engage is connected to lie behind the adjacent stop 2. Preferably ner: A plate 6 L-shaped incross-section is secured against the inner side and back of the stop. Near the lower enda transverse cut- 7 is formed in the back of the plate 6, and the metal below the cut is sprung outwardly to space it somewhat from the stop. This enables the tongue 5 of the adjacent metal strip to be inserted through the slit 7 The lower part of the plate 6 thus forms a keeper 8 for the tongue 5. c 1

In order that thetongue 5 should gnot be too long 1 preferably extend a cut :9 partway down from the out? at the angle of the plate. The upper part of the keeper 8 thus this keeper is formed in the'following manthus located where is free at both sides so that it may be sprung out as much as may be necessary to "enable the tongue 5 to pass in behind it. It is necessary also to provide a stop of some kind to limit the outward swing of the'screen on one or both of the plates 6. I therefore provide a hook 10 which hook is preferably formed of a tongue integral with the plate 6 above the keeper 8 and bent to form a hook directed toward the screenbut lying entirely behind the stop. VVh-en the screen is swung outwardly, the flange 4- contacts with this hook asshown particularly in Fig.2. a a It should be specially noted that boththe keeper 8 and the hook 10 are locatedv entirely behind the stop so that the window opening is entirelyclearand these parts are they are least likely to be damaged. 1 i

To insure the connectioniof' the metal strips 3 to the screen being strong enough and to assist in properly positioning the same, I provideeach of the metal strips 3 with a flange 11 oppositely directedto the flange 4. This flange lies flush against one of the surfaces of the screen and the fastenings securing the strip to the screen may be passed through this flange, though it is preferable also to drive some of the fastenings through the body'of the strip.

The, advantages of the specific attaching means employed should not be lost sight of. Four pieces only are required, two for attachment to the screen and two for attachment to the window frame. I The parts at- V tached to the screen extend continually from top to bottom leaving no-gaps or openings at any point. The attachments to the window frame leave the window opening absolutely unobstructed. The parts all being constructed of metal stampings are exceedingly cheap-and may be made with absolute accuracy so that all parts are interchangeable.

What I claim as my" invention is 1. The combination of a window frame and sash; ascreen fitted between side members of the window frame out of alinement with the sash, and swingable between said members to bring its upper end into or out of position below saidsash metal strips secured to the ends of the screen and each provided with a flange adapted, when the screen is'swung to a position below the sash, to engage the outer side of one of the window frame members aforesaid; and a hook secured to the window frame limiting the outward swing of the screen.' L

2. The combination of a window frame and sash; a screen fitted between side members of the window frame out of alinement with the sash; metal stripssecured to the ends of the screen each provided with a laterally' extendingifla'nge terminating in a downwardly extending tongue; and a keeper behind and secured to each of the aforesaid side members with which said tongues may be engaged to form pivots on which the screen may be swung to or from a position with its upper end below the sash and the said flanges engaging the outer sides of the window frame membersaforesaid.

' 3. The combination of a' window frame and sash; a screen fitted between side members of the'window frame out of alinement with the sash; metal strips secured to the ends of the screen each provided with a laterally extending'flange terminating in a provided along one edge with a flangesubr stantially'jat'right angles to the plateQthe strip being slit at the narrow end to form a tongue-of the'lower'end-of the flange. in combination with a part for attachment to astop of the window frame comprising a metal plate -=L-shaped; in 'cross-section adapted to-fltthe-face' and back' of a stop and cut transversely tofo'rm at its: lower end a'flat plate or keeper andadjacent its upper end provided with a flat 'hook integral with'the plateat the same side'as the keeper and-directed-toward th'eangle of theplate.
